Toddler Help Blow Out Candles not available on Picnic Tables

My Sim hosted a birthday party for his toddler at Oasis Springs Desert Bloom Park. Cooked the cake at home, brought it to the party and put it on one of the stone picnic tables. The interactions for the Birthday cake allowed child, teen, and adult Sims to blow out candle and Age up child, teen, and adult Sim, but the Help to Blow Out Candles was not there, so I was not able to age up the toddler Sim to a child Sim. The toddler did not have the interactions to ask for help blowing out candles either.

The cake was centered and the candles were lit. Aging up options were available for all the Sims except for the birthday toddler Sim. There was an option for the adult Sim to grab a piece of the lit birthday cake for the toddler, which should not have been available while the cake had lit birthday candles on it.
